TO ALL WHOM IT MAY CONCERN:

Be it known that I, W. A. C; OAKS, of Reading, the county of Berks, andState of Pennsylvania, have invented a new and useful Improvement inWindow-Shade Fixtures; and I do hereby declare that the following `is afull, clear, and exact description of the same, referencebeing had tothe accompanying drawings, making a portion of this specification, inwhich- Figure 1 is a front view of a shade-ixture constructed accordingto my invention. Figure 2 is a longitudinal transverse section o 'thesame. Similar lettersfof reference indicate corresponding parts in bothfigures. This invention relates to that variety of devices employed toretain the cords of windcwshades in position, and its object is toprovide an eicient fixture for thc purpose named, which will be moresimple in construction, and consequently capable of being manufacturedat a much less cost-than those hitherto in use.

The invention consists in` the combination of a recessed guide-plateorframe, a tension-slide, and a fiat zigzag spring, whereby the desiredobject is secured. i

To enable others to understand the construction and operation of myinvention, I will proceed to describe it with reference to the drawings.g i

A represents the guide-plate, which receives and holds the'other orworking parts of the xture, and which lis designed to be secured to thewindow-frame, by screws passing through lugs a, ofappropriate form,provided upon the said gui'de-plate, as shown more fully in fig. 1.Formed in the back or rear side ,of the guide-V plate A is alongitudinal recess, 6, preferably of nearly or quite rectangular shapein its`transverse section, and which has placed in its.V innermostportion, as shown more clearly in fig; 2, a spring, c, formed of a stripof any suitable sheet metal, bent into zigzagY shape, as indicated indotted outline in iig. 1, and which, having two fiat sides, is enabledto play within the narrow space allotted to it. Situated behind thespring just l described, and in the outer or back portion of the recessb f the guide-plate, is the tensionslide B, the main length of lwhich isof flattened form, and at the lower end of which is aninwardly-extending spur or shoulder,- b, againstv which bears the lowerend of the spring c, the upper end of the said spring resting againstthe top a ofthe guide-plate, the said top a being cut away at its hackpart to permit the slide B to extend past the same, as more plainlyrepresented in iig. 2. The said slide is furnished, alt its upperextremity, with a hook, d, or like means, whereby the shade-cord may beattached thereto, as hereinafter further set forth, a.nd which.v extendsforward over the guide-plate, .and to which the shade-cord may beattached in the usal manner, as indicated in red outline in the fig.2,just mentioned. When the fixture is secured to the window-frame,.ashereinbefore explained, the spring c and the slide B arc-retainedinproper positionby-tbe surface of such window-frame closing the back orrear side of the recess, in which the said parts are placed.' The springc,. by pressing downward the hooked slide B, of course draws upon the'cor-d attached, as hereinbefore mentioned, to the hook el thereof, andretains the same at the required degree of tension.

V From the small number of parts involved in the construction of thexture,and the convenience with which they may be tted together, the saidfixture may be manufactured at a cost much less than-that of thosehitherto devised,'without at all detracting from the eii'icientoperation of the-same -when in use.

What I claim as my invention, .and desire to secure by Letters Patent,is-

The combination of the recessed guide-plate A, the zigzag spring c,'andthe slide B, substantially as and for the purpose specied.
